While a preferred embodiment of the invention is illustrated in thedrawings, it will be understood that minor changes and modifications maybe made in the particular construction shown and the invention may beembodied in other forms as will appeal to those skilled in the art andfalling within the scope of the appended claims without departing fromthe spirit of the invention.

Referring to a detail description of the particular embodiment of theinvention illustrated in the drawings, A generally designates asupporting stand and casing having a base l9 and walls 29 extendingupwardly from opposite sides thereof connected by a front wall 21, thebase I9 and the forward reduced portions of the side walls 29 extending,as shown, forwardly of the front wall 2 l.

Supported on the side walls 29, at the upper ends thereof, is anauxiliary frame 13 having thereon two bearings 22, in which is supportedfor rotation a shaft 23. Rotary movement is imparted to the shaft 23 byan electric motor (not shown) mounted within the lower part of the standor casing A, through driving means including a gear wheel 24 fixed onthe shaft 23 between the bearings 22 meshing with a smaller gear wheel25 on a shaft 26 on the forward end of which there is a pulley 21. Thedriving means, which includes other elements, not shown, and theconstruction of the auxiliary frame B, as well as the construction ofthe supporting stand and casing A, are the same in construction as thatdisclosed in our application Serial No. ,623.

The shaft 23 projects forwardly from the front wall 2! of the supportingstand or casing A, and, on this end of the shaft, is mounted the vesselcarrier 28, the same being of disc-like form adapted to carry at thefront side thereof a plurality of tumbling essels 29 of various sizesand shapes, each individually detachably secured at one end on thecarrier. In accordance with the present invention, the vessel carrier 28is connected with the projecting end portion of the shaft 23 so that itis disposed forwardly of the end of the shaft with its central partspaced therefrom whereby substantially the entire face of the vesselcarrier is left free for the mounting of tumbling vessels thereon. This.connecting means includes a metal disc 30 fixedly secured on the end ofthe shaft 23, and a plurality of studs 3| on the vessel carrier 23projecting from the rear face thereof at points outwardly of thecentral-part of the same, and having their outer threaded end portions52 extending through apertures 33 in said disc, said studs each havingan intermediate enlarged portion 34 interposed between the rear face ofthe vessel carrier 28 and the disc 30.

On the outer threaded end portions of the studs are nuts '35., The studs3| have reduced inner end portions 36 fitting in apertures 3! in thevessel carrier and secured by welding thereto. The disc 39 is shownprovided with a central opening 38 receiving the projecting end portionof the shaft 23 and is secured by welding to the shaft.

For the sake of clearness, only two tumbling vessels or containers 29are shown attached to the vessel carrier 28 in Fig. l of the drawings.It will be understood that the invention comprehends havingtumblingvessels attached'to the vessel carrier 28 all about the front facethereof. Means is provided for individually and removably mountingtumbling vessels on the carrier 28 at places located different distancesradially from the axis of rotation of the vessel carrier and alsocentrally thereof. The vessel carrier 28 is shown provided with amultiplicity of apertures 39 arranged in circular series concentric withits axis of rotation and with an aperture 49 centrally thereof. Themeans for detachably securing the tumbling vessels 29 on the vesselcarrier includes a plurality of holders 4i, each comprising a base 42having an annular marginal flange 43 at the upper side thereof, thisflange having an outer inwardly extending annular portion .4. Projectingfrom the rear face of the base 42 centrally thereof is a stud 45 adaptedto engage any one of the apertures 39 and 49 in the vessel carrier,

and 46 is a nut to engage the outer end of the stud. The base 42 of theholder 4! is shown of dished formation with its concave side facingdownwardly, this construction insuring a firm bearing of the base of theholder against the face of the vessel carrier 28, and when the nut 46 istightened, this tends to flex the base 42 and draw inwardly the annularmarginal flange 43 of the holder.

Each tumbling vessel 29 is provided on its lower closed end with anannular flange or collar 41, this flange or collar being convenientlyformed as a separate part and secured as by welding to the bottom wallof the tumbling vessel. On the outer side of the annular flange orcollar 41 is an elongated arcuate lock lug 48. The lug 49 is shown ascircular in cross section and secured to the flange at its under sideand ends by a metal bond 49. Supported on the annular collar or flange47 for transverse movement in line with the lock lug 48 is a latch orlock bolt 50, the forward end portion of said latch or lock bolt, whichhas a beveled end face 5!, working in a slot 52 in the annular flange orcollar 4'! and the latch or lock bolt being supported at its rear end bya guide plate 53, the latter having a slot 54 through which the rear endportion of the latch or look bolt extends.

The annular flange or collar 41 of the turnbling vessel is adapted tofit within the annular flange 43 of the holder 4| with the lock lugfitting against the underside of the outer inwardly extending annularflange portion 44 of the holder and with the slidable latch or lock boltforced outwardly to bear against the inner side of the inwardly extendinannular portion 44 of the flange 43 0f the holder at a pointsubstantially diametrically opposite said lock lug, the lower end of theannular flange 41 being forced downwardly against the base 42 of theholder H by the wedging action of the lug 48 and beveled face portion 5|of the latch engaging the inwardly inclined under face of the outerinwardly extending portion 44 of the flange 43, so that the tumblingvessel is firmly and securely fastened to the holder.

Operating means for the latch or look bolt 59 is provided that isoperable from the outer end of the tumbling vessel and which providesfor forcing the latch or look bolt 59, under spring tension, against theouter inwardly extending portion 44 of the flange 43 of the holder.

The operating means for the sliding latch or look bolt comprises a shaft55 extending longitudinally along the outer side of the tumbling vesselmounted for rotation in bearing brackets 56 and 51 on the side wall ofthe tumbling vessel 29 at the upper and lower ends thereof, the lowerbearing bracket 59 being shown open at one side and having apertures 58in side portions thereof, the shaft 55 being retained in the bearingbracket 56 by a pin 59 engaging the apertures 58. On the lower end ofthe shaft 55, is a crank 60 to which is connected, at one end, a lever6|, said lever extending through a guide slot 62 in the flange 41and'having a laterally extending por tion63 at its other end providedwith an aperture'64 through which extends the rear reduced end portionof the sliding latch or lock bolt 50. A cotter pin 65 engaging anaperture 68 in the rear portion of the latch or lock bolt 50 at the rearside of the laterally extending end portion 63 of the lever 6| serves asan abutment to limit the longitudinal movement of said lever in onedirection relatively to the latch or look bolt 50. Interposed betweenthe laterally extending end portion 63 of the lever 61 and a shoulder6'! on the latch or lock bolt 58, is a coiled expansion spring 68.Fixedly secured on the upper end of the shaft 55 is a sleeve 69. thelower end of said sleeve rotatably fitting on the upper face of theupper bearing bracket 51. The sleeve 69 extends beyond the outer end ofthe tumbling vessel 29 and connected to the outer end of said sleeve isa hand lever that is adapted to be swung laterally for turning the shaft55 to actuate the latch or lock bolt 50. When the hand lever 10 is inthe position shown in full lines in Fig. 7, the lock or latch 50. is inits retracted position illustrated in Fig. 8 of the drawings. When thelatch or look bolt 58 is in looking position, as shown in Fig. 6, thehand lever 10 is in the position shown in dotted lines in Fig. 7. Whenthe latch or lock bolt 50 is in locking position, forced under tensionof the expansion spring 68, the crank 80 is past the dead center pointand thus serves as locking means to maintain the latch or look bolt 50in locking position.

Each tumbling vessel 29 has a pair of cover attaching ears H projectingforwardly from the outer end thereof, said ears being arranged tocooperate with the hand lever 10 to lock the latter when the same hasbeen swung to move the latch or;,lock bolt into locking position and inits retracted position. The hand lever 10 is connected at one end to theouter end of the sleeve 69 for limited movement in the longitudinalplane of the shaft 55 so that the hand lever 10, as it approaches theend of its stroke, can be raised to pass by the adjacent attaching ear Hand positioned back of saidattaching ear H as shown in Fig. 7 of thedrawings. The end portion 12 of the hand lever 10 is mounted in a slot13 in the upper part of the sleeve -68 and pivotally connected theretoby a pin 14. Slidable in the upper part of the sleeve 69 is a plunger 15that is pressed outwardly by a spring 16 interposed betweenv the innerend of the plunger 15 and the upper end of the shaft 55, said plungerhaving a head 11 at its outer end to bear against an inclined faceportion 18 on the end portion 12 of the hand lever. As will beunderstood; the spring-pressed plunger 15 acts to yieldably maintain thehand lever 10 substantially parallel with the outer end of the tumblingvessel 29 so that, when the hand lever 18' is released and dropped backof the adjacent cover attaching ear 1 I, it will be held locked in thisposition.

I The tumbling vessels or containers 29, when interlocked with theholders 4| attached directly to the vessel carrier 23 as hereinbeforedescribed, are disposed parallel with the axis of rotation of the vesselcarrier. The means for detachably securing the tumbling vessels on thecarrier includes means providing for mounting the tumbling vesselssothat the same will be disposed at an inclinationlto the axis of rotationof the carrier as well as parallel thereto. The means for this purposecomprises a plurality of adapter members in opposite legs thereof andsecured thereto. On the base plate of the angle bracket, at the underside=thereof, are lugs 83, and the base plate has a threaded stud 84fixedly secured thereto and,

projecting from the rear face thereof, said stud being adapted to beengaged with any of the apertures 39, 40 in the vessel carrier 28 anddetachably secured thereto by a wing nut 85 on the stud.

The supporting plate 8| of each angle bracket is provided with anaperture 86 to receive the stud 45 of any one of the holders 4|, thebase 42 of the holder fitting on the supporting plate 8| of the anglebracket and being detachably secured thereto by the nut 46. As will beunderstood, the base plate 80 of the angle bracket can be secured to thevessel carrier 28 in different positions of adjustment about its axis sothat the angular position of each tumbling vessel relatively to the axisof rotation of thevessel carrier can be varied. Each of the tumblingvessels 29 is provided at its outer end with a removable cover 81, andwith cover fastening means comprising the ears H and atransverse lockbar 88 rotatably engaging outwardly projecting elongated bearings 89 onthe outer side of the cover 81, the end portions of the lock bar 88being adapted to be engaged with slots 90 in the ears II. Fixed on thelock bar 88 is an eccentric 9| which is disposed between the bearings 89and adapted to engage the outer face of the cover 81, the elongatedbearings 89 allowing limited bodily outward and inward movement of thelock bar 88 therein. Secured on the eccentric 9| is a hand lever 92 forturning the lock bar 88. As will be understood, when the hand lever isswung to the position illustrated in Fig. 1 of the drawings, the cover81 will be tightly clampedon the end of the tumbling vessel.
